The UnderGrowth vs Idle Deepcore

Deep beneath the surface, a living network stirs. You are the cultivator — tap to grow, produce to expand, and unlock the hidden species of the underground. The UnderGrowth is an idle clicker built around the slow, satisfying rhythm of fungal growth. Tap to generate mycelium, watch your production tick upward, and make strategic choices about when to prestige and how to spend your hard-earned spores. GROW YOUR NETWORK Tap the screen to produce mycelium and build your underground operation. Upgrade your production rate and watch your numbers climb — even while you're away. UNLOCK RARE SPECIES Discover and collect a variety of unique underground species, each with its own look and lore. Watch your ecosystem come to life as your collection grows. PRESTIGE & EVOLVE When the time is right, reset your progress and carry forward bonus spores that make each run more powerful than the last. Every prestige brings new potential. BOOST YOUR OPERATION Earn temporary boosts through rewarded ads — double your production for an hour, multiply your tap power, or claim an instant burst of progress. For players who want a permanent edge, the Shop offers one-time upgrades that stay with you forever. BUILT FOR IDLE PLAY Your mycelium keeps growing whether you're actively tapping or not. Check back, collect your haul, and keep expanding. No energy timers. No pay-to-win walls. Just the quiet satisfaction of watching something grow.

Idle Deepcore is a pixel-art idle mining game about digging from the surface all the way down to the planet's molten core — and beyond, into orbit. Tap to break blocks and collect ore, then buy machines — jackhammers, steam drills, seismic hammers, excavators and more — to mine for you, even while you're away. The deeper you dig, the rarer the ore and the tougher the blocks. FEATURES • Tap-to-mine with crunchy pixel-art feedback • Automate with a roster of upgradeable mining machines • Smelt raw ore into valuable ingots in your furnaces • Descend through distinct biomes to ever-deeper layers • Prestige to reset for permanent power and unlock new systems • Skill tree, mastery nodes and a research lab to specialize each run • Build a rocket and mine asteroids out in orbit • Offline progress — your machines keep mining while the app is closed • Cloud save via Game Center — back up and restore your progress • Playable in 29 languages Optional rewarded ads can double your offline haul — never required to progress. Dig deeper. Get richer. Idle Deepcore.
